Zinco14532323 has well addressed much of what I meant. (Thank you, Zinco.)

Your parents raised you in certain ways; you are now interacting with young people whose parents raised them in ways different from what you knew in your early life. There's great potential for unintentional miscommunication.

Also, you are greatly concerned about how your depression may affect or be understood by your parents. On the background of your upbringing, you may feel bad for feeling bad. You are suffering with depression, and you may feel guilty for suffering with depression.

This is what I meant by adding guilt.

Try - it's not easy - to allow yourself to simply be sad or depressed without piling guilt on top of that sadness. One way to try is by acknowledging the feelings and thoughts without fighting them, and then relax and let the thoughts go. If the thoughts return, let them return; say "hello," relax and let them go again.

Over time the thoughts and feelings may not visit so often.

I'm glad you are in a singing group. I wish you success and as much joy as you can handle.
